How to Freeze Whey

Related Articles

Whey is one of two principal proteins found in milk. Whey is the liquid by-product from cheese and yogurt production, while the second major protein, casein, curdles to form the dairy product. Its powdered form is used as a nutritional supplement for muscle recovery and strengthening. Whey can replace water or milk in baking or serve as a fat alternative for low-fat ice cream. According to MayoClinic.com, consuming whey protein may help prevent heart disease, diabetes and genetic disorders such as allergies. You can freeze whey to use later and to prolong its shelf life.

Pour whey into an airtight container. Look for containers that are advertised as “freezer safe” or “freezer quality.” Airtight containers protect your whey from being contaminated by other items in the freezer, and they keep out air, which may cause discoloration to the whey. Leave about an inch at the top of the container for expansion. Alternatively, use a zip-close freezer bag.

Seal the container or zip-close bag firmly. Use a permanent marker to write the date on a stickable label.

Place the labeled whey in the freezer and use it within three to six months.

Tip

When you are ready to use the whey, defrost it for 24 hours and do not refreeze it.

Alternatively, fill ice cube trays with whey protein and then place the frozen whey cubes in a plastic bag. Put the ice cube trays on a flat surface in the freezer and cover them to prevent any other liquids in the freezer from contaminating the whey.

Use several containers to freeze the whey in portion sizes.

Warning

The Mayo Clinic warns that people on medication that affects blood sugar levels, diabetics and patients with hypoglycemia should use whey with caution, as it may lower blood sugar levels. Consult a doctor before using whey.
